Os níveis de aptidão física dos adolescentes são um importante indicador de seu estilo de vida e podem prevenir o desenvolvimento de fatores de risco cardiometabólicos. Este estudo teve como objetivo comparar os fatores de risco cardiometabólicos em adolescente a partir das mudanças nos componentes de aptidão física relacionada à saúde após três anos de seguimento. Foram realizados testes motores segundo o manual do FITNESSGRAM (back-saver sit and reach; curl-up; push-up; e progressive aerobic cardiovascular endurance run) e foram avaliados os fatores de risco cardiometabólicos: circunferência de cintura; pressão arterial em repouso; HDL colesterol; triglicerídeos; e glicemia em jejum em dois momentos (2014 e 2017). Para comparar os fatores de risco cardiometabólicos a partir das mudanças dos componentes de aptidão física entre os períodos de acompanhamento foi aplicado o teste de Kruskal-Wallis ou ANOVA one-way. Foi observado melhora significativa dos componentes de AFRS com o passar dos anos, com exceção da aptidão cardiorrespiratória. Não foram identificadas diferenças estatísticas nos fatores de risco cardiometabólicos a partir da manutenção ou mudanças dos componentes de AFRS durante o período de acompanhamento.
Background: Postmenopausal women typically present loss of bone mineral density (BMD), muscular strength, and postural balance. However, there is no consensus in the literature on the correlation between these variables. Objectives: Our objective was to verify the correlation between BMD, isokinetic peak torque of knee extensors and flexors, and static postural balance in postmenopausal women. Methods: Fifty-one postmenopausal women underwent BMD evaluation through dual-energy X-ray absorptiometry (DXA) for four bone regions (lumbar spine, femoral neck, total hip, and trochanter). Muscular strength of knee extensors and flexors was evaluated in an isokinetic dynamometer at 60 and 180 degrees per second in the dominant lower limb. Static postural balance was evaluated on a force platform during five different tasks (bipodal eyes open, bipodal eyes closed, semi-tandem eyes open, semi-tandem eyes closed, and unipodal). Statistical analysis involved Spearman's correlation coefficient (rho). Results: There was no significant correlation between BMD and isokinetic peak torque of knee extensors and flexors. Approximately half (27 of 60) of the postural balance variables presented significant inverse correlations (p < 0.05) with BMD and of these, the majority (22 of 27) presented moderate correlation (rho between -0.49 and -0.30). Most correlations were for bipodal support tasks with eyes open and eyes closed. Conclusion: Greater postural oscillation in different balance tasks was correlated with lower BMD in postmenopausal women. Therefore, it is suggested that intervention protocols for women with impaired BMD, especially osteoporotic, consider balance training as part of rehabilitation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
